Notes. Forecast Fisher marginalised errors (in % of fiducial value) on AGN clustering depending on the survey parameters (survey depth and solid angle). eRASS4,6 and 8 correspond to two, three, and four years of the all-sky survey. Photo-z accuracy parameters are σ0 = 0.03 and ffail = 0.1 (see Sect. 6.2 for further details).
